NATURAL SELECTION

Natural selection was proposed by

Darwin reflects key principle in quiz on natural selection, where evolutionary mechanisms shape genetic variation and adaptation. In this context, Darwin aligns with experimental and theoretical evidence from population genetics, behavioral ecology and molecular phylogeny. Textbooks like Campbell Biology, Futuyma Evolution and Hartl Principles illustrate supporting data. Understanding why Darwin fits helps integrate natural selection, environment.

NATURAL SELECTION

Sexual selection is mainly driven by

Sexual selection, proposed by Darwin in 1871, favors traits increasing mating success rather than survival, via intrasexual competition among same sex and intersexual choice where choosier sex, often females investing more in gametes, selects mates. It explains elaborate ornaments, good genes indicators like MHC diversity and parasite resistance per Hamilton-Zuk hypothesis. Fisherian runaway and handicap principles describe coevolution of preference and trait. Therefore Mate choice describes process enhancing reproductive rather than viability fitness. This concept integrates genetics, ecology and molecular evidence, frequently tested in NEET, GATE and CSIR-NET, highlighting links between genotype, phenotype and environment.
